Pytest学习之使用多个fixture

#使用多个fixture
#如果用例需要用到多个fixture的返回数据，fixture也可以return一个元组、list或字典，然后从里面取出对应数据。

import pytest
@pytest.fixture()
def user():
    print("获取用户名")
    a ="nuo"
    b="123456"
    return (a,b)

def test_1(user):
    u=user[0]
    p=user[1]
    print("测试账号：%s,密码“%s"%(u,p))
    assert u =="nuo"

if __name__ == '__main__':
    pytest.main(["-s","fixtures.py"])

#
# #当然也可以分开定义成多个fixture，然后test_用例传多个fixture参数
import pytest
@pytest.fixture()
def user():
    print("获取用户名")
    a="nuo"
    return a
@pytest.fixture()
def psw():
    print("获取密码")
    b="123456"
    return b

def test_1(user,psw):
    '''传多个fixture'''
    print("测试账号：%s,测试密码：%s"%(user,psw))
    assert user == "nuo"

if __name__ == '__main__':
    pytest.main(["-s","fixtures.py"])

# #fixture与fixture互相调用
@pytest.fixture()
def first():
    print("获取用户名")
    a ="nuo"
    return a

@pytest.fixture()
def second(first):
    '''pswd调用user fixture'''
    a=first
    b="1234556"
    return (a,b)

def test_1(second):
    '''用例传fixture'''
    print("测试账号：%s,密码：%s"%(second[0],second[1]))
    assert second[0]=="nuo"

if __name__ == '__main__':
    pytest.main(["-s","fixtures.py"])


'''fixture的scope=session 跨.py文件调用'''
def test_2(first):
    '''用例传fixture'''
    print("测试账号：%s"%first)
    assert first == "nuo"

if __name__ == '__main__':
    pytest.main(["-s","fixtures.py"])
